Space Ghost is a title character who flies in space fighting villains like Zorak, Brak, & Moltar.
In his original incarnation, he was a superhero who, with his sidekick teen helpers Jan, Jace, and Blip the monkey, fought supervillains in outer space. In the 1990s, the character was brought back as a host for his own fictional late-night talk show, Space Ghost Coast to Coast, on Cartoon Network and Adult Swim. In the 2000s, he was revamped as a serious superhero once again in a mini-series by DC Comics.
